Abstract

Phases of variable composition Cd_{1 – x}M_xB₄O₇ (0 ≤ x ≤ 0.07), M = Tb, Eu. T.N. KHAMAGANOVA (Baikal Institute of Nature Management, SB RAS, Ulan-Ude).

Phases of variable composition Cd_{1 – x}M_xB₄O₇ (0 ≤ x ≤ 0.05), M = Eu and Cd_{1 – x}M_xB₄O₇ (0 ≤ x ≤ 0.07), M = Tb were synthesized by solid-state reactions. The crystallographic characteristics of the obtained phases (space group Pbca) were determined. Thermoluminescence studies of the synthesized phases excited by ultraviolet radiation have been carried out. It is shown that samples with a content of 3 mol.% of active Tb and Eu ions have the maximum luminescence.
